Biology Lecturer Interview Questions and Answers

Proto-oncogenes are present in all cells.

• Proto-oncogenes are normal genes that regulate cell growth and division.

• They can be found in all cells of the body.

• Mutations in proto-oncogenes can lead to their activation and transformation into oncogenes, which can cause cancer.

• Examples of proto-oncogenes include c-Myc, Ras, and Bcl-2.

Currently, there is no scientific evidence to suggest that any organism has self consciousness.

• Self consciousness is a complex concept that is difficult to define and measure.

• While some animals exhibit behaviors that suggest they may have some level of self awareness, such as recognizing themselves in a mirror, this does not necessarily indicate true self consciousness.

• Research in this area is ongoing and there is much debate among scientists about which organisms, if any, po...read more

Formen Ovale is a small hole in the fetal heart that allows blood to bypass the lungs.

• Allows blood to bypass the lungs

• Closes after birth

• Helps in fetal circulation

• May cause complications if not closed properly

Zymogens are inactive enzymes that require activation by cleavage of one or more peptide bonds.

• Zymogens are also known as proenzymes.

• They are synthesized and stored in an inactive form to prevent damage to the cells that produce them.

• Activation of zymogens occurs through proteolytic cleavage, which removes inhibitory peptides and exposes the active site.

• Examples of zymogens include trypsinogen, chymotrypsinogen, and prothrombin.

• Zymogens play an important role in regulating en...read more

Digestion is the process of breaking down larger food particles into simple absorbable form.

• Digestion starts in the mouth with the help of saliva and enzymes.

• The stomach further breaks down food with the help of acid and enzymes.

• The small intestine absorbs nutrients and minerals from the broken-down food.

• The large intestine absorbs water and electrolytes from the remaining waste before excretion.

• Examples of digestive enzymes include amylase, protease, and lipase.
